Why Do Some OLEDs Have Motion Blur?

Blur Busters:

The flicker of impulse-driven displays (CRT) shortens the frame samples, and eliminates eye-tracking based motion blur. This is why CRT displays have less motion blur than LCD’s, even though LCD pixel response times (1ms-2ms) are recently finally matching phosphor decay times of a CRT (with medium-persistence phosphor). Sample-and-hold displays continuously display frames for the whole refresh. As a result, a 60Hz refresh is displayed for a whole 1/60th of a second (16.7 milliseconds).
